Main bearings, crush?

I bought a 383 stroker that is complete and the block and heads are already machined, but it is not assembled. The guy I bought it from already put the crank and new bearings in the block, but I want to take the crank and bearings out to clean all the passages, measure and inspect just so I can be sure. Do the bearings get crushed after tightening? Is there a risk of spinning a bearing down the road if a bearing gets taken out and put back too many times?

You can re-use the bearings with no problem. The amount of "crush" on the bearings will still be there as long as the bearing bores are not modified..

An excellent idea to clean all the galleries! Peace of mind knowing for sure it is correctly done.

If the mains are line bored, theoretically the bores are all exactly the same diameter. But when I run into this situation I make double sure they go back into the exact same location anyway.

Put them into the block with the saddles and caps dry. Oil only on the crank surfaces when the crank goes in.
